Title: Improvements in unidirectional drive-transmitting devices
IPC: F16D31/08
Filed: 1944-02-07
Abstract: 584,922. Variable-speed gearing. DEMOCRATIS, A., KAMMER, G. S., and REILLY, C. O. C. Feb. 7, 1944, No. 2256. [Class 80 (ii)] [Also in Group XXIX] An hydraulic mechanism for permitting rotation of a shaft in one direction only, comprises a number of pistons 6 surrounding the shaft and reciprocated thereby, in cylinders 1 each of which has a non-return valve 15 held open during one half of each rotation, the direction of rotation being determined by selection of the group of valves so held open. So long as the shaft rotates in one direction the pistons merely pump liquid to and from the hollow shafts 5, but any movement in the opposite direction effects a hydraulic lock. The mechanism is primarily for use with a variable speed gear of the type in which weights 29, Fig. 8, rotated about eccentrics 31 on the driven shaft by a driving member 27, impart an alternating torque to the driven shaft; and its effect is to permit rotation of the driven shaft by torque acting in one direction only. Thus the said shaft is driven by a series of impulses, and in order to smooth these out, a spring coupling 34 is interposed in the transmission. For details of the hydraulic mechanism see Group XXIX. Specification 562,570 is referred to in the Provisional Specification.

Abstract: 607,686. Air inlets operating under supersonic velocity conditions. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., CHESHIRE, L. J., and SMITH, A. G. Feb. 1, 1945, No. 2609. [Class 4] [Also in Group XXXV] An air inlet for a fluid-flow diffuser system, such as a gas turbine for an aircraft, intended to operate under supersonic velocity conditions and affected by a shock-wave when so operating, is of variable area so that the whole of the airflow presented to the inlet may be made to pass therethrough, means being provided to indicate variations in a characteristic condition at the inlet and thereby the inlet area adjustment required to ensure that the whole of the airflow will pass through the inlet. In the form shown in Figs. 3, 6a and 6b, an aircraft wing is formed with an air duct 6, the inlet area of which is adjustable by means of flaps -8 operated by jacks 9. A casing 16 mounted on the axis of the duct is provided with three static pressure heads A, B, C arranged so that under correct operating conditions the shockwave 2 is located between B and C. Under such conditions the pressures at A and B are equal and less than that at C, while if the wave moves upstream of B the pressure at that point will rise to the value at C. Pressure gauges may be connected to the points A, B, C and variations in their readings due to movement of the shock-wave utilized by the pilot for the manual control of the jacks 9 to make appropriate adjustments of the area of the air inlet. Preferably, however, the movement of the shock-wave is utilized to effect automatic adjustment of the flaps 8. In the arrangement shown in Figs. 6a and 6b, the pressure heads A, B, C are connected to pairs of capsules 25, 26 and 27, 28 respectively, the capsules being connected to pivoted members 31, 32 connected to the elements 37a, 37b, and 41a, 42a of electric control switches.
